OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE -ject of said invention is to provide an efficient tabulating mechanism, whereby the carria 'e maybe moved to any desired columnar field without first arresting the carriage at a preceding columnar field.

A further object of my invention is to provide efficient denominational or decimal tabulating mechanism whereby the carriage may be arrested at any desired denominational or decimal position within the selected columnar field.

A still further object of my invention is to provide eflicient carriage controlling mechanism which may be thrown into operation when the tabulating mechanism'is actuated, to control the speed of the. carriage during the tabulating operation.

Another object of my invention is to provide mechanism to regulate'the velocity of the typewriter carriage when the same is released from its step-by-ste letter spacing mechanism, and particular y to provide a positive speed controlling mechanism adustable to a redetermined speed.

A still furt er object of my invention is to provide'such mechanism as will offer ractically no resistance to the motion of tlie carriage until the latter has acquired,--under the pull of its driving means, a certain redetermined velocity under which it Wil be safe from injury if suddenly stopped in its motion by other devices on the machine, as the margin stops or the tabulator stops.

To theabove and other ends which will hereinafter appear, my invention consists in the features of construction,arrangements of parts and combinations of devices to be ereinafter-described' and particularly point ed out'in the appended claims. v

base 1, corner posts 2 and a top'plate 3.

Key levers 4 for the printing instrumentali ties (not shown) are fulcrumed. on a fulcrum plate 5 which is secured to the base 1 of the machine and are provided with the usual finger keys 6. These key levers are connected to return springs 7 and may be connected in any suitable manner to the type bars. The printing key levers are guided in sawkerfsin the upright member 8 of an angular plate 8*, thus forming a front comb for the printing key levers. The plate 8 also has a substantially horizontally dis osed portion 9 apertured to receive the tabu ator key stems 10. Thus a single plate 8 constitutes a guide for the printing key levers and also for the tabulator key stems at the front of the machine. The top plate 3 has upwardly projecting lugs 11 which support fixed grooved tracks 12 that-receive anti-friction rollers 13 interposed between said tracks and tracks 14 of the carriage 15, a construction which affords a free travel'ot' the carriage. The usual carriage scale 15 is employed to cooperate with a suitable pointer. The carriage15 supports a cylindrical platen 16'and a feed rack 17, the latter being connected to arms 18 which are pivoted to the carriage at 19 in order that the rack may be raised and disengaged from its feed pinion 2O (Fig.5) operatively connected to an escape'ment wheel 2]. through the usual shaft and .back clutch mechanism, such as is employed in the No. 6 l tcniington machine. The shaft for the escapcinent wheel is supported in a "at its rear end which is substantially U-shaped in cross section, and the outer face or edge of the bearing is concaved or recessed as indicated at 27. .The opening formed between the side arms of each U-shaped hearing 24 constitutes a recess in which the reduced rectangular portion 28 of the rack bar 26 may be seated, the shape of the bearing conforming substantially to the shape of the part 28. It should be understood that one of these reduced portions 28 is provided at each end of the rack bar-and is received in an. open bearing in each of the sup orting brackets, similar to that shown in igs. 14 and 20. The left-hand end of the rack bar is threaded at 29 for a nut 30 whichhas a face 31 that cooperates with arecesse'd portion, such as 27, in the outer edge of the eft-hand bearing 24 v A lock nut 32 may also be provided to secure the adjustable nut 30 in its adjusted position. that this arrangement affords a longitudinal adjustment of the column stop rod or rack It Will be seen bar in its bearings, in order that it may be properly positioned to bring the stops thereon in proper lateral relation with the column selector and. decimal stops. The right-hand end of the rack bar is likewise threaded as at 33 for cooperation with an adjustable nut 34 and with a locking nut 35.

A sleeve or collar 36 is mounted on the threaded end of the column stop bar and the position thereof isregulated by the nut 34.

may he readily grasped to slide the locking bolt on the rack bar against the tension of the sprin 87, and thus withdraw the face 40 from the ockmg recess 27 in the bearing 24 R 7 on one side of each rao so that the rack bar may be raised, and re moved from its supporting brackets 24. This construction provides means for readily removing the rack bar from the machine, so

5 that if desired a rack bar with difi'erently arranged column stop stituted for the bar in use. Thus one rack bar may have the sto s arranged thereon accord-,

ing to one pn'nte form or blank and another 10 rack bar may have the stops arranged in accordance with another character of blank and one rack bar may be uickly substituted for-another accordin to t e particular blank employed. The rac bar 26 is preferably ooved at letter B acr distances apart on the rout and rear sidiis thereof as indicated at 42, the grooves being arranged opposite each other.

The coil erating column orrack stops 43 are prefera ly of the form shown in detail in Figs. 16, 17, and 17* from which it will be seen that they are each bifurcated at 44 to provide parallel side walls 45 which are re-.

ceived 1n the recesses or grooves 42 in the rack bar. It will likewise be observed that each stop is provided with a parallel extension or ou a into one of the adjacent grooves in the column stop or rack bar to afford additional support to the sto Each stop has a flat face on one side an is oft-set on'the opposite side thereof to reinforce the stop and form a carrier for the engagin member or pro'ec tion 46. The rearward y rojecting flat face l: stop constitutes an engaging face with which the decimal stop levers cooperate, whereas the depending end of the flat face 48 constitutes a portion with which the column selecting means engage, all as will hereinafter more clearly appear. Each of the rack stops has alined transverse recesses 01' openings 49 which are about (:0 I incident with the bottom faceof the rack bar 26 when the stops are properly placed thereon and alocking bar 50 is received within the notches and locks the stops against removal or accidental displacement from the rack bar. The locking bar 50 extends along the rack bar and has inclined slots 51 therein and 50 through which extend headed screws 52 which are received in threaded openings in the rack bar The heads of the screws 52 connect the locking bar to the rack bar, and a coiled contractile spring .C? is connected at 5 one end 54 to the locking-bar and at its 0 posite end to a stud 55 that extends throug 1 an oblique o ening 56 in the locking bar, into the. stop ar. y A' finger piece 57 is formed from the locking barat one end thereof, by 60 means of which it can be pushed endwise. The spring 53 tends to maintain the locking barin the locking position shown in Figs. 15 and 16, that is to say, with the bar seated in the recesses 49 in'the column stops so that the stops are locked against removal from s thereon may be sub recesses or slots 49 in the rack sto 's, so that a ing rib 46 which likewise takes such the bar. When, however, pressure is exerted upon the finger piece 57 to move it toward the right, a slight longitudinal movement of the locking bar will be effected and at the same time there will be atransverse movement of the bar produced by the screw and slot connection 51 'and 52. This lateral or transverse movement of the bar is suflicient to remove it from engagement with the 15 they are free to beremoved from t e ban and to be adjusted to different points'alon the same. In order to facilitate such adjustment the top of the stop bar may be provided with a scale which, in a general way, corresponds to the carriage scale of the machine, as indicated in Fig. 2. Fronran examination of Figs. 1, 6 and 7 it will be seen that the depending portions 48 of the rack stops extend downwardly different distances from the rack bar. By means of this construction, which differentiates the rack stops one from another, and cooperating mechanism, the carriage may be arrested in any desired columnar position without first arresting it at preceding columnar positions.

I will now. describe the column selectin means. In the desi n illustrated, four o the tabulating keys which I have designated in Fi 2 by the reference numeral 58, control the column selecting mechanism, though it should be understood that a greater'or less number of such 'keys' may be utilized, b providing the tabulator rack bar with the pro or number of rack stops. Thus, it five rac stops are used, which is ordinarily suflicient, four column selecting keys 58 will be necessary, as will hereinafter more clearly appear. The keys are provided with indices as the numerals 2, 3, 4, and 5 and the rack stops 43 may likewise be provided with corresponding indices, so that they can easily be placed on the rack bar in their proper order. The columnating keys are preferably arranged two on each side of the set oi denominational or decimal keys 59 and at opposite sides of the keyboard of the machine, though they may be otherwise arranged. Each key stem 10 of the tabulating keys, whether they be denominational keys 59 or column selecting keys 58, is made in the same manner, preferably b folding a sheet metal strip into substantially u-shapc in cross section so that the loop-like port-ion or edge of the stem is presented toward the f front of the machine. Each kcy head or ca is formed from a blank such as is shown in Fig. 13, with the port-ions 60 thereof pmjecting from opposite sides of the head. The blank is afterward struck up in the form shown in Fig. 12, so as to bring the portions 60 together to form a shankwbich is received within the upper end of the key stem and riveted in positionby rivets 6] passing through the key stem and the shank-on the Zen-- described each key stem key cap, thus firmly uniting the cap to the key stem. An aperture 62 is formed in the round edge of the key stem 10 by punching a strip 63 therefrom. This strip is bent inward to a form to afiord a smooth bearing for the tabulator key lever end 65, which passes between-the side walls of the stem and through the opening 62 therein. As heretofore asses through an opening in the portion 9 oi the angular plate 8 and the lower end of each stem likewise passes through an opening in a lower guide plate 66, preferably formed by bending up the plate at 67 in the manner shown in Fig. 9 and sawing across the upper bent portion of the plate, so as to form a series of saw- I kerfs or openings that extend through the seated in openings in its base.

plate and "form guides for the tabulator key stems 10. The plate 66 is likewise bent or formed with a trough-like portion 68 to receive a pad 68 against which the projection 69 on the angular tabulator key levers 64 strike when the'tabulator keys are depressed to their lowermost position. The various angular tabulator key levers 64 are assembled on a pivot shaft 70 (Fig. 3), which extends across the machine from side to side and is Collars 71 are secured to the rod by set screws 71 and abut against the inside of the base to prevent an endwise shifting movement of the rod. It will be observed that sleeves or hubs 72 separate each pair of tabulator key levers to maintain them properly spaced apart. Each spacing sleeve may be in the nature of a hub connected to its associated an ular lever 64, and sleeves 72 secured to t e rod 70 by screws 72 prevent the hubs 7 2 from moving longitudinally on the pivot rod.

Each tabulator key lever 64 has one end of a contractile restoring spring 73 connect-- ed thereto at'74, (Fig. 9), the opposite end of said spring being connected to the rear flange 66 of the lower key stem guide 66, as indicated at 7 5. Each tabular key lever is likewise apertured for the reception of the pivot pin 76 forming part of the ordinary spring clip 78 of the push rod 77. Each push rod 77 is preferably a two-part rod joined by a screw threaded connection 80'to permit a lengthening or shortening of the rod. The rear end of each push rod 77 has a key hole slot 81 in the flattened portion thereof for cooperation with the stem 82- of a headed stud which projects laterally vfrom a crank arm 83 secured to a rock shaft 84. The enlarged opening 85 at the rear end of the slot 81 enables the head 82 of the stud. to pass through the opening, thus permitting an assemblage of the parts. When the pin is in the narrow portion of the slot 81 the' head prevents a disconnection of the push rod from the in. T he rock shaft 84 is mounted upon pivot screws 86 (Fig. 4) with cone bearings, which screws extend through threaded openings in the base 1 of the machine.- Locking nuts 87 are provided to secure the pivot screws against accidental displacement. In the normal position of the parts the forward ends of all the slots 81 in the different ush rods bear against the pins 82. On re'ercnce to Figs. '1 and 9 it will be seen. that the rock shaft 84 has a forwardly and upwardly projecting arm 88 secured thereto. The upper free end of this arm is apertured to receive the laterall 'pro jecting pin 89 of an ordinary pivot 0 1p 91 forming part of an u right pull rod 90. The upper end of the pu 1 rod 90 is pivotally connected at 93 to carriage releasing mechanism which will be hereinafter more clearly described.

Each of the push rods 77 is adapted to contact at its rear end with what 1 term a differential or selector universal bar 94 which, as shown in Figs. 9 and 10, is form 'l of a single piece of sheet metal, provide? it its ends with upwardly extending integral arms 95 that are pivoted on the rock shaft 84 and with a stiffening flange 94 at its lower edge. Returning springs 94" (Fig. 3) are connected to said bar at opposite ends thereof and to a stud 94 extending from the base of the machine. From an inspection of Fig. 10 it will be seen that the ends of the four push rods 77 are normally located at different distances from the cooperating bearing faces 96, 97, 98-and 99 on the forwardly extending flan e 94 of the selector universal bar. Thus t e ush rod 77 at the right hand side of the mac 'ine, which is'connected to the key bearing the numeral2 and which effects an operation of the column selecting means to cooperate with the first stop 43 to select the second column on the pa er, is in contact with the bar in the normal position of the parts, whereas the second push rod from the right, which is controlled by the column key bearing the numeral 3 is a short distance from the coperating contact face of the selecting bar in thenormal position of the parts, the two remaining rods 77, counting from right to 4 left, being' at gradually increasing distances from their coperating contact faces. In this manner the selecting bar will be taken up sooner or later by the diilierent push rods and a greater or less extent of movement will be transmitted thereto, depending on which of thefour. column selecting keys is actuated. The movement thus transmitted to the selecting'bar produces adownward movement of an arm 100' secured at 101 thereto. This arm 100 is shaped like the arm 88 and extends forwardly and upwardly to an upright link or pull rod 102, the upper end ol" which pivoted at 103 to a crank arm 104 (see l igs. and 7). The crank arm 104 is rigidly connected to or formed integral with a sleeve 165 which is secured to the rock shaft 106 by a set screw 107. The rock shaft near the left-hand end thereof has a stepped stop "108 secured thereto, the edge'of the stoph'aving steps or stops 109 thereon, whereasthe working'fac'e or a side of the stop piece is in a single plane extending fore and aft of the machine.

It will be understood that the extent'of movement transmitted to the selecting bar 94 will determinetheextent of rocking movement transmitted to the shaft 106', and that this in turn will move the multiple stop 108 to different extents fore and aft of the ma- -cl1ine around the axis of the shaft to bring rearmost portion or step 109 thereof into oooperation with the" first column stop 43, counting from left to ri ht when lookin from the front of the machine in Fig. 2, an

writin 'may take place in the second columnar fie d located between the first and second column stops; whereas if the column selecting key bearing theindex numeral 5 be depressed, the selecting bar will not be moved so far and the first stop or step 109on the rotary stop 108 will be movedto a position where it will cooperate with the fourth column stop 43 of the series, counting from left to right in Fig. 2', and writing may take place in the fifth columnar field to the right of thefourth column stop. It follows therefore that the extent of movement transmitted to the rotary column selecting stop 108 determines the position of columnar arrest of'the carriage or the columnar field at which s'aid carriage shall be arrested and that cedmg'stops' If thecarriage be the carriage will not be arrested by the prein the ex tr'eme'ri hthand position and it is desired to select a enominational position,.it is merel necessaryto depress the appropriate denominational key 59 and it will cooperate with the first columnar stop, arresting the carriage in thedesired denominational position in the first columnar field,or in that space which is to the'left of the first column sto in Fig. 2, when looking from the front of t e machine or in the column onthe paper which is at the left-hand side thereof. For this reason it is unnecessary to provide a number 1 column key or a special key forthe first column.

While I have referred herein to the stops 43 as column stops it will be understood that saidstops have atwo-rfoldfunction; that is to say, the same stops locate and determine stops and that the columnar fields by cooperating with the column selecting stop 108 to bring about the arrest of the carriage at the proper columnar ficld'and they'also cooperate with the denominational stops 153 to effect an arrest of the carriage at the roper denominational POSitlOliWltlliIl the se ected field. The construction and arrangement of the parts is such that a columnar 'field may be selected, say for instance, the second columnar field which is between the first and second column stops, and then the name John Doe may be written within the first part of the field and this may be followed by the numerals 7,268.25 for instance, which may be pro e'rly located within this same field by the d nominational stop mechanism as in the following example John Doe 7,268.25 John Roe James Smith 1,181. Frank Brown 1,451. Frank Whlte.1,254.10 GeotBlack 5,126.05

Thus from an inspection of Fig. 6 it will be observed that the column determining stop 108 is situated to the left of the series of denominational stops 153, looking from the front of the machine, and thateach column I or rack stop43 passes to the left of the entire series of denominational stops before it cooperates with the column selecting stop.. It follows therefore that after any given column stop, say, for example, the first, andthe column selecting sto are brought into cooperation, the name (lbhn Doe'may be written in the firstpart of the second column and that a subsequent operation of the thousands denominational 'key will project the corresponding denominational stop 153 into the path of the next succeedin or second column stop and that the nuinera s 7,268.25 may then be written within the same columnar field and not in the next columnar field as was usually the case heretofore. It will also be seen that the column determining stop 108 issituated about four letter space distances from the decimal or left hand denominational stop. This arrangement provides roper space between columns and assures at east two letter space distances between the last written character in one column and the first written character in the next succeeding column, as for example, when characters are written in the tenths position at the last part of a columnar field, thus 7,268.25, and this is innnediately followed at the first part of then-ext columnarfield with writing as shown in the foregoing, example.

The relative arrangement of the mdices on the rack bar 26 and the denominational and column selecting stops is such that a rack stop set on the bar in accordance with any particular index numeral will effect the arrest of the carriage at a corresponding numeral'o'n the carriage scale when the runof the carriage-is efiected 'byacolumn deter- I mining key. If, for instance, a racklstop 43 be set at the index numeral 45 on the stop bar and the requisite column selecting key without actuating the selecting stop 108,

then the carriage will not be arrested ac cording to the indices on the stop rod but will be arrested four letter s ace distances earlier than it would if'a co umn selecting key is employed to secure the position. For example, if a stop 43 is set on the rack bar at the index numeral 45 on the stop rod and the left-hand denominational stop 153 is successively actuated until said stop 43 is brought into cotiperation therewith, then the carriage will not be arrested at 45 on the carriage scale but at 41. This is due to setting of the'column determining sto 108 four letter space distances to the le of the left-hand denominational sto as has been described. It is desirable t erefore for the operator to secure the columnar position wholly by an actuation of the column selecting means when the column selecting and'denominational means are both used in the same machine and to utilize the denomi national sto s wholly for securing the denominationa position within a selected columnar field. When, however, the de nominational mechanism alone is employed, then. the indiceson the stop rod 26 should correspond in arrangement to the carriage scale 15", so that when a column stop is set at, say, 46 on the stop rod and the lefthand denominational stop is actuated, then the carriage will be arrested at 46 on the carriage scale. It should also be observed that the first columnar field is located between the beginning of the line on the pa er and the position determined by the fi ist column stop; or in other words, in the space on the paper to the left of the position defined by the first column stop, so that writing may take place at the first part of a line and this may be followed in the same columnar field by numerals, the positions of which are determined by the'denominational tabulating mechanism, whereas ordinarily it IS necessary in other machines to write the numerals in the second columnar field or in the space between the first and second column stops. While the column selecting mechanism is being actuated in the manner hereinbefore described, the release of the carriage and the connection of the carriage.

to thecarriage-speed controlling means 18 being effected. Thus the upper end of the pull rod 90 is pivoted at 93, Figs. 5 and 7, to a crank arm 110which is connected to or forms part of a sleeve 11] that is mounted to turn on a rock shaft 106. The sleeve 111 has formed as a part thereof, or connected therewith, a carriage releasing device and the sleeve and carriage releasing device are prevented from moving longitudinally on the shaft by the collar 105, hereinbefore de scribed, and by a collar 113 which is secured to the shaft by a' screw releasing device comprises a cam 115 secured to or formed as a art of the sleeve 111 and to the left-hand side of the cam in Fig. 5 is formed a shoulder 116 which is concentric 114. This carriage with the axis of the shaft 106 for K511170805 which will hereinafter ap ear. antifriction roller 117 projects aterally from a releasing lever 118 to which it is pivoted, and the roller bears against the cam 115, and under certain conditions against the concentric face 116 on' the releasing device. From an inspection of Figs. 29 and 30, it will be seen that the lever 118 has a substantially right angular bent portion 119 at the rear end thereof, and the terminal of the portion 119 is pivoted by a screw 120 to one arm of a U- sha ed bracket 121 secured to the to plate 3 of the machine by screws 121". tion 119 of the releasing lever or arm has a gear 122 pivoted at 123 to rotate thereon. The gear 122 has a pinion 124 connected to or formed integral therewith, and this gear meshes with a driving pinion 125 pivoted to the bracket 121 by a screw pivot 125 It will be seen that the swinging movement of the release lever or arm 118119 is around the pivot screw 120 as a center, and that this pivotal center is coincident with the pivotal center of the driving pinion 125. It will also be seen that in the bodily movement of the gear 122 with the releasing lever 1 1 81 19, the pivotal axis of the gear will describe an arc, the center of which 'is coincident with the pivotal center of the driving pinion 125, so that no matter what the position of thereleasing lever il18-119, the gear 122 will always remain in mesh with the pinion 1 25.

T ie por A lever or vibratory device 126 is pivoted to the bracket 121 by a screw pivot 127 and is adapted to oscillate like the pendulum of a clock. This lever or vibratory device has an elongated slot 128 extending longitudinally thereof and a laterally projecting pin 129 on the pinion takes into this slot and as the pinion rotates, a vibratory'motion. will be transmitted to the lever 126. A weight 130 is slotted at 180 (Fig. 28) and the heads-130 of rivets 130 overlap the slot 180 and prevent a lateral withdrawal of the weight from the lever 126 but afford a longitudinal or sliding movement of the weight on the lever. Beneath the weight and surrounding the lever 126 is a coiled expansion spring 131 which is supported at its lower end by a nut 131 carried by and adjustable on the lever 126 and held against accidental displacement by a check npt 131". The purpose of this 15 weighted lever 126.

ter of the lever, so as to provide more or less resistance to the movement of the lever by.

the pinion 125 and also to afford an automatic movement ofthe weight on the lever away from and toward the pivotal center of said lever.

In the normal positions of the parts the carriage feed rack 17 is in the full line position shown in Fig. 30 where it is just above and out of contact with the pinion 124. At

this time there is no connection whatever between the feed rack and the device for controlling the speed of the carriage which comprises the gears 122, 124, 125 and the When, however, the column selecting key is actuated, motion is transmitted through the associated angular lever 64, push rod 77, rock shaft 84, crank arm 88 and pullrod 90 to the cam 115 which,

20 when turned from the full line to the dotted line position in Fig. 30, turns the lever 118-119 on its pivot 120. The effect of this movement is to elevate the gear 122 and the integral pinion 124 to the dotted line position shown in Fig. 30, thus bringing the pinion 124 into mesh with the teeth on the feed rack and elevating the rack to the dotted line position where it is disengaged from the carriage feed pinion 20. This movement disengaging the feed rack from its pinion also throws'the carriage controlling device into cooperation with the carriage so that when it is released from the feed pinion and starts to move, under the power of the spring drum (not shown) motion will be transmitted by the feed rack to the pinion 124 and through the pinion to its integral gear 122, and from the gear 122 to the pinion 125, and the rotation of the pinion 125 will cause the lever 126 40 to be vibrated, thus offering a resistance to the movement of the carriage and enabling it to move under control of the vibrating lever at the desired rate of speed, which may 7 be determined by an adjustment of the weight 130. The speed of vibration of the pendulum or vibratory device will be increased directly in proportion to the velocity of the spring-driven carriage and while practically no resistance is offered to the pendulum or vibratory device until'its speed of vibration has reached acertain point, due to its effective length, the resistance offered by the pendulum will increase rapidly after its speed has reached and passed the natural speed of vibration due to its length. The

effective length of its pendulum will be increased automaticall by reason of the centrifugal force throwing the weight against the spring and away from the center of vibration of the pendulum, causing its natural rate of vibration to be lessened. When the resistance, including that offered by the vibrating pendulum, equals the pull of the spring (not shown) on the carriage, the latter Will maintain a uniform velocity until an rested. It will be understood that this equalizing of the resistance to the pull may be readily ell'ected by varying the position of the we ight 130 on the vibrating arm and that this may be accomplished either by lengthening or stiffening the spring 131 or by moving the same toward or away from the pivotal center of the lever by means of the set nut 131, so that within the capacity of the machine, any determined speed may be obtained. When a column selecting ke has been depressed and the stop 108 has een moved to the desired position and the carriage is released in the manner hereinbefore described, it is desirable to automatically throw the carriage speed controlling device out of operation and to automatically restore the carriage to the control of its stepby-step feed mechanism when-the carriage 85, has completed its run and the column selecting and cooperating column step has been brought into contact; and frir this purpose I provide means that are automaticall actuated and controlled by the run of t 1e car riage. Thus the shaft is mounted in its bearings to move longitudinally for a limited distance, as well as ,to rotate. The bearing 132 at the right-hand end of the shaft, looking from the front of the machine, '95 is apertured to afford a longitudinal as well as a turning movement of the shaft 106.- The left-hand bearing 133 is constructed as shown in detail in Fig. 8 of the drawings with athimble 134 which is seated in an opening in the bearing or lug 133 and is adapted to receive a cylindrical enlargement 135 on the shaft 106. A coiled expansion spring 136 bears at one end against the bottom 137 of the thimble and at its opposite end against a shoulder 138 formed by the cylindrical enlargement 135 on the shaft. The tension of the spring 136 is therefore exerted to maintain the shaft 106 at the limit of its longitudinal movement toward the right. A stop 139 is adapted to turn on a headed screw pivot 140, the threaded end of which is received in an opening in the bearing or lug 133, so that the step has a pivotal movement around the screw as a pivot. The stop is bifurcated, as indicated at 141, so as to providestop members 142, 143 which cooperate with a fixed pin 144 carried by the bearing stud 133 and projecting into the bifurcated portion of the stop 139 to limit the turning movement of said stop. The stop 139 has a curved contact'face 145 which is eccentric to the pivotal center of the stop and extends into the path of movement of the stop 108 as it moves bodily with the shaft 106 from right to left. It will be seen that the construction is such that when the rock shaft 106 receives a longitudinal movement from right to left, it will cause a corresponding movement of the cam 115, and

' that the anti-friction roller 11?, which hears on the cam, will drop from the face of the cam to the concentric portion 116 thereof. The eii'ect of this dropping movement of the anti-friction roller on the cam is to lower the releasclever 118-419 to its normal position, thereby restoring thegear 122 to its lowermost position, thus to engage its feed pinion 20 and automatically disconnect the rack from the speed controlling device. 'ed when a column-stop carried by the carriage contacts with the column selecting stop 108 and the impact of the carriage moves the shaft 106 from right to left until the column selecting stop 108 is forced into contact with the stop .139. This movemfent, as heretofore pointed out, effects an automatic disengagement of the carriage controlling mechanism and restores the carriage to the control of the feed pinion 20 and to the ordinary stepby-step carriage feed mechanism. When pressure is released upon the column selecting key, the rotation of the column selecting stop 108 to the normal position will take place, and during this movement of the stop 108 the stop 139 will turn on its pivot 140 and the limit of such turning movement oi the stop 142 and 144. The purpose of this movement of the stop 139 is to prevent the pressure of the carriage upon the parts from overcoming a restorative movement of the stop 108 and its associated parts to the normal position. Thus-by pivo ting the stop 139 in the manner described, and providing an eccentric face thereon, an easy movemerit of the stop 108 to its normal position its normal position shown is afforded; the lowest portion of the eccen' tric face being gradually brought into cooperation with the stop 10% as stop 139 turns upon its. pivot and when the feed rack has become rengag'cd all pressure of the carriage will be taken up by the feed rack and feed union and pressure between the and the stop 108 will engaged column stop released by the slight be relieved or wholly lateral movement of the stop 108 through turning movement of the eccentric faced stop 139. When the step 108 has been restored to its normal position and pressure is released upon the stop 139, it is restored to in Fig. 5, by a 146 that surrounds the pivot coilcd spring and is secured at one end 147 to the stop and at its opposite end 1418 to the hearing 133.

I will now proceed to describe the denominational tahulating mechanism, which may he used to determine the proper denominational position of arrest of the-carriage within the selected columnar field. From an inspection of Fig. 2 it will be seen that the denominational keys 59 hear indices designating the decimal, units, tens, hundreds, thousands, tens of thousands, hundreds of enabling the feed rack 17 This operation is effect-- 139 is determined by the stops pivot eaaese push rods 150 to its angular lever and its denominational stop lever is the same as the connections heretofore described between the angular levers 64 and the push rods 77 and restoring springs 149 are em'pldyed to restore the angular levers 1 19 and the associated parts to their normal positions. I he restoring s rings 149 are constructed and connected ike the springs 73.hereinhefore described. Each denominational stop lever 153 extends upwardly. andlorwardly at its upper end where it forms a stop which coo' crates with the column stops 43. Each of t e levers 153 has a notch 15 1 in the rear edge thereoi for cooperation with a pivot 155 (see Fig. 31). The pivot 155 is shown in detail Fig. 19;iirom which it will be seen that washer-like projections 156 are formed on the pivot to constitute spacingmeans for the different denominational stop levers at the pivotal'portions'thereof. The civot 155 is provide with a threaded end 157 which takes into a threaded open' the frame 158 (Figs. 1 and 18), for t levers, the'other or headed end 159 of the hein seated in an alined o ening at the other side of the frame 158. rod 160 extends from side to side of the'frame 158 forward of the levers 153 and at about the level of the pivot 155, as indicated in Fig. 31

to prevent an accidental displacement of the levers from their pivots. The rod 160 has a threaded end 160 (see Fig. 18) which is received in a tapped opening in one side of the frame 15%, the opposite end r'od bein seated a hearing in the opposite side of t e frame 158v it will be seen that the various stop levers 153 are rounded at 161cc as to ali'ord amovement of the levers on their pivot and yet coo crate with the stop pin 160 at any point int c movement of the lovers to prevent a displacement of the levers from their pivot. levers 153 are bent laterally as shown in Fig. so as to compensate for the diilerence in width between the system of actuating means therefor at the lower ends of the levers and the stop carrying oortions at the upper ends of the levers. The frame 158 extends outwardly at the lower portion thereof to conform tot-he system oi levers 153 and a bearing opening or socket 162 is formed in e stop or head of the Various of the the bottom edge of the frame 158 at each sidethereof for co peration with a stud 163 car ried by the base of the machine and which has a spherical bcarin head for cooperation with the socket. Th1s hinged joint constitutes a hen ring for the frame 158 at the lower end thereof and on which the frame is adapted to turn toward and from the machine, whereas, the upper end of the frame is secured to depending lugs 164 which project from the top )late and are situated on opposite sides of the frame 158. Screws 165 extend through the lugs and are received in openings 166 in the frame 158, so as to secure the frame in place. The top plate of the machine is cut a way at the rear edge thereof to receive the frame 158 and the denominational stop levers and to afford a free fore and aft movement of the latter. The outline of the opening is shown in Fig. 5 from which it will be seen that the frame 158 fits snugly within the opening in the top plate and that the screws 165 firmly secure the frame in place'and that the top plate itself revcnts a lateral displacement of the frame.

y these means I provide a structure in which the frame 158 as a whole, together with the denominational stop levers, may be moved from the full line to the dotted line position to give access to the escapement mechanism and other parts of the machine by merely removing the screws 165. When the frame 158 and the stop levers are turned back to the dotted line position, they turn on the bearings 162 and 163.

The frame 158 has a forwardly extending shelf-like projection 158 (see Figs. 1, 3 an 31) which is slotted in its forward edge to form a comb-plate for cooperation with the stop levers which are received in the slits and are properly spaccd and guided by the combplate thus formed. The construction of the stop levers and the frame 158 and the manner of mounting the same in the machine, afford a ready assemblage of the parts and they may be quickly removed when desired for the purpose of repair.

As heretofore pointed out, the upper for: wardly extending ends of the stop levers 153 cooperate with the rear sides of thecolumn stops'43 when the stoplevers are actuated by their ke s 59. A universal or decimal stop release ar 167 (Figs. 31 and 32) extends across the system of levers 153 at the lower ends thereof so that a rearward movement of any of the stop levers causes a corresponding movement of the universal bar. This bar is doubled on itself at the central engaging portion thereof and has n wardlv extending side arms 168 of a sing e thic ess of metal which are pivoted at 169 to the forward extension 158 of the frame 158 so that the universal bar is adapted to vibrate around the pivots 169. The bar 167 is apertured at 170 for cooperation with a hook 171 on a link 172, the rear end of which is slotted at 173 for 006 eration with a headed pin 174 which has an integral octagonal portion 174 for co6 oration with a wrench on the side of the lin opposite the head and a threaded extension 17 4' passes through a slot 175 in a crank arm 176 rigidly connected to the rock shaft 84. A nut 175 secures the pin 174174174 in any desired osition to which it may be adjusted along t is slot 175 to regulate the timim of the take up of the crank arm 176 by theTink 172. The slot 173 has an enlarged terminal portion 173 throu h which the head of the pin 174 is receive The slot 173 affords a movement of the rock shaft 84 and arm 176, when actuatedthrough the sclectim bar 94, in the manner hereinbefore described, by any of the column selecting keys without affecting the bar 167. When, however, a denominational key is depressed, a rearward movement is transmitted to the associated push rod 150 by the angular lever 149, thus producing a rearward movement of the lower end of the associated stop lever 153. This movement is effective to move the release bar 167 toward the rear of the machine and to move the link 172 to turn the rock shaft 84. The pin and slot connections between the push rods 77 and the crank arms 83 enable the shaft 84 to be thus turned without affecting the selectin bar or the push bars which actuate it. i T. 1e turning movement of the rock shaft 84 effects an operation of the carriage releasin mechanism in the manner hereinbefore escribedand at the same time that the carriage is released, the carriage speed controlling device is automatically thrown into 0 oration. When the carriage is released y an actuation of a denominational key and is arrested by the projection of the associated denominational sto into the ath of one of the column stops, the force of the impact between the stops is borne by the engaged column stop, by the stop bar 26, by the rojected denominational stop and by the f fame 158 which supports the same, and in this event no automatic ren agement of the releasing device by impact between the stops is effected, the parts merely resuming their normal positions when pressure on the denominational key is released.

In addition-to effecting a release of the carriage through an operation of either the column selecting or denominational keys, I provide an additional key 177 at the keyoard of the machine for releasing the carriage without interposing the tabulator stops. The key 177 is connected to a key lever 178 which is similar in form to the printing key levers 4 and like said lovers 4 it is fulcrumed on the fulcrum plate 5. The ke lever 178 is preferably situated at the leftand side of" formed thereon, the construction being'such that an elongated slot 180 is formed between the finger 179 and the body of the key lever. This slot 180 receives a pin 181 which projects laterally from an angular lever 182 that is like the angular levers 64 and 149, except that the forwardly projecting finger on each of said levers which cooperate with the associated key stem is omitted from the lever 182. The angular lever 182 is adapted to turn on the pivot rod 70 and is pivotally connected at 183 to a rearwardly extending twopart push rod 184 which corresponds to the push rod 77 heretofore described, and like said rods has an elongated o ening 185 in the rear flattened end portion thereof for the-reception of a laterally projecting headed pin 186 which projects from a crank .arm 187 secured to the rock shaft 84. From an inspection of Fig. 10 itwill be observed that the forwardly extending edge 94 of the angular selecting bar 94 is entirely cut away opposite the rear end of the push rod 184, so

that the full rearward movement of the push rod may take place without it contacting with the selecting bar. It will follow from this construction that on a depression of the release key 177 a downward motionwill be transmitted to the forward end of the angu-v lar lever 182 by reason of the. in and slot connection 180-181 between t e key lever and angular sub-lever and that this move.- ment of the sub-lever effects a rearward movement of the push rod 184 which vi-.

brates the'crank arm 187, thus turning the rock shaft 84 which is effective to produce a downward pull of the rod 90, thus releasing the carriage in the manner hereinbefore described through the cam 115 and at the same time automatically connecting the carriage s eed controlling device with the carriage.

en pressure on the key 177 is released the parts will be restored to their normal posi-- tions and the carriage Will be rengaged with restoring spring 188, which is like the springs its step-by -step letter feed mechanism. .A

73 and 149*, is connected to the part 66 and to the angular lever 182 to restore said lever and its associated parts to thenormal positions. I

Foot brackets 189 (Fig. 22) are each secured by screws 190 (Fig. 1) to a side of the base at the forward part of the machine. Each bracket has inwardly projecting ears 191 to which the plate 66 is secured by screws 192 and a curved or semi-cylindrical threaded inwardly curved portion 193 is formed on each bracket and a corresponding oppositely disposed semicylindrical un- Lhreaded depression is formed in the base of the frame, so that the base-and each bracket together have an opening which is threaded on one side and'in which a rubber foot, 194

is seated. v

Each of the crank arms 83, 88, 176 and 187 ected columnar field.

emcee (Fig. 11) which are connected to the shaft 84' are preferably rigidly mounted on the reduced end 195 of a hub-like slee've 196 which in turn is fastenedrto the shaft by a pin 197 which extends through the sleeve and into the shaft.

In the operation of the device, a key' 58 isfirst depressed to move the stop 108 to select ing stop 108. When the-two stops are in contact the pressure. exerted by the usual carriage spring (not shown) or the impact between t e stopswill overcome the pressure exerted by the spring 136 and the rock shaft 106 with the stop 108 thereon will be moved to the left until the stop'108 contacts with the pivoted. stop 139. This longitudinal movement ofthe shaft 106 to the left likewise moves the earn 115 to the left and away from the roller 117 which drops on the concentric portion 116 on the cam, thus'allowing the feed rack to drop back into ongagement with the feed pihion 20 and automatically disconnecting the carriage control-, 7

ling devices from the carriage. This automatic restoration of the carriage to theconr trol of its feed, mechanism is effected-instantl broug t into contact and is efiected by the when two stops 43 and 108 are.

run of the carria e itself. When pressure on the depressed ey 58 is released the restoring springs 73 and 94 cause the various parts of the column jumping or column selecting mechanism to be restored to their normal positions. During the rotary return movementof the stop 108 tonormal'position it will have a rolling contact on thearresting stop139 and the stop 139 will turn with it,

and as the lower portion ofthe eccentric face thereon is reached it will afford a further slight movement of the sto%108 to the left, thus releasing all pressure etween the engaged stop 48 and the stop 108, the carriage emg held at this time by its, feed pinion and it cannot follow the stop 108. As pressure is released between the stops 43 and 108, the stops 108 and 139 will fly ack to their nor- Thesemeans enable the stop 108 to be easily -restored and revent the pressure on the carriage from olding the stop 108 in its projected position. The proper denominational key is next depressed and the associated stop will be projected formal positions.

It should be understood that the parts are so timed that the proper step 109 on the col umn arresting stop .108, whether it be the first or the last step 109, is interposed in the path of the 006 crating column stop before or at the time t e carriage is released. In other words, the diflerential throw given to the stop 108 through the selecting bar and its connections is such that the r uisite step 109 will be interposed in the p:- t 1 of its column stop by the time the cam 115 has been turned far enough to release the rack.

From certain aspects of my invention the stops 43, 108 and 153. may be regarded generally as tabulator stops, and from certain other aspects of the invention the stops 43 may be regarded as column stops, or stops that have the two-fold function of cooperating with the column selecting and denominational mechanism, whereas the stop 108 may be regarded as a column determining or column selecting stop and the stops 153, or the stop engaging portions of the levers 153, may be regarded as denominational or decimal stops.

l/Vhile I have shown one embodiment of my invention, it should be understood that various changes may be made without departing from the invention, and some of the features may be employed without others.
